PROBLEM TO BE SOLVED: To prevent efficiency of a heat storage tank from being reduced because the heat storage operation and the heat release operation are performed at the same time since piping of a heat source system and an air conditioning system is connected in the tank, in a conventional air conditioning system using the heat storage tank. SOLUTION: This system includes a first system 8, a second system 9 and a third system 10. The system 8 circulates from a heat source device 1 via a parallel passage of a plurality of air conditioners 4 to the device 1. The system 9 circulates through a heat exchanger for heat storage. The system 10 goes from the downstream side of the parallel passage to the upper stream side of the heat exchanger for heat storage. An opening/closing valve is placed on each system. The system also includes a water supply system 14 that circulates from a water intake side of the heat storage tank 3 to a water return side via the heat exchanger for heat storage. The water supply system constitutes a water intake passage 16 on high and low temperature sides within the heat storage tank via a mixing valve 15 on the upper stream side of the heat exchanger for heat storage, and a water return passage 18 on the high and low temperature sides via a switching valve 17 on the downstream side of the heat exchanger.
